The invention belongs to the technical field of microorganisms, and discloses a method for increasing the yield of extracellular polysaccharide through co-fermentation of phellinus linteus and inonotus hispidus, prepared polysaccharide and application, the phellinus linteus and the inonotus hispidus play a synergistic effect through the method, the yield of fungus extracellular polysaccharide is increased, and the anti-tumor activity of the fungus extracellular polysaccharide is improved. According to the method, the phellinus linteus linteus and the inonotus hispidus are utilized for co-fermentation for the first time, and on the basis of optimizing a fermentation culture medium, rich enzyme systems of the phellinus linteus linteus and the inonotus hispidus are utilized for fully converting a fermentation substrate, so that the yield of the exopolysaccharides is increased, and the antitumor activity of the exopolysaccharides is improved; and a material basis is provided for the development of phellinus linte
